Abstract: A system, method, software and related functions are provided for managing activity in a radio frequency band that is shared, both in frequency and time, by signals of multiple types. An example of such a frequency band is an unlicensed frequency band. Radio frequency energy in the frequency band is captured at one or more devices and/or locations in a region where activity in the frequency band is happening. Signals occurring in the frequency band are detected by sampling part or the entire frequency band for time intervals. Signal pulse energy in the band is detected and is used to classify signals according to signal type. Using knowledge of the types of signals occurring in the frequency band and other spectrum activity related statistics (referred to as spectrum intelligence), actions can be taken in a device or network of devices to avoid interfering with other signals, and in general to optimize simultaneous use of the frequency band with the other signals.

Abstract: The present invention provides network management of a network or multiple networks, using a Web client, and including multimedia and hypermedia capability. The present invention provides a unified, remote, graphical, transparent interface for Web users, working at a Web client, to a variety of managed networks. The present invention receives requests from a Web client forwarded by a Web server and interacts with the managed networks and their associated objects to obtain information. The present invention then converts this information in real time to hypermedia document format in HTTP and HTML, and transmits this information to the Web client via the Web server, appearing to the client as if the information received were a Web file ab initio. This permits a Web user to manage multiple networks and access multiple networks via a single Web client, thus providing a unification of the management interface for dissimilar managed networks, and devices.

Abstract: A system that provides supporting software to allow facsimile documents to be transferred via non-traditional mechanisms such as electronic mail, the Internet, and V.32 or other non-fax modems. The system allows facsimile documents to be transferred by computer without intermediate G3 facsimile hardware and without performing time-consuming compatibility determinations. The system also provides for cross-platform document transmissions.

Abstract: The Real-Time Embedded Software Repository Apparatus fully characterizes, evaluates, and reuses real-time embedded software that is placed or stored in a repository database. The Repository System comprises at least one Repository Client and at least one Repository Server and utilizes simulation and translational techniques to allow Real Time Embedded Software (RTES) to be re-used, played, and evaluated on various desktop development environments or target operating environments. The Repository System organizes and processes Repository files as Repository Units which may comprise Software Source Files and Test Software. Repository Units also contain Attachments that provide current and historic information to static files that are stored in the Repository. The Repository Units are further characterized using analysis tools (software analysis) which allow the user to associate fixed and user defined Attributes to the RTES.

Abstract: An electronic key telephone system is disclosed that provides a plurality of telephone features and functions, while only requiring a four-wire line between the central equipment and each key-set telephone (KST) and a two-wire line between the central equipment and each single-line telephone (SLT). Linear delta coding and time division multiplex (TDM) techniques are used to eliminate the multiple pairs required in traditional private business exchange (PBX) systems between the remote key telephones and the control unit. In the present system, a microprocessor controlled TDM controller transmits and receives control signals serially to and from interfaces in the system for control purposes and also for establishing exchange of digitized audio information data between selected interfaces. The system thus exchanges digitized audio information directly between interfaces and provides control signalling between the TDM controller and the interfaces, with all of the exchanges being done in real time.
